Two U.S. soldiers stationed in South Korea are accused of raping two teens. There are 28,500 American troops stationed in the country.

Two American soldiers have been accused of raping teenage girls in two separate incidents in South Korea, sparking protests near the U.S. Embassy in Seoul.

The public outcry led Army Brig. Gen. David Conboy –who overseas the U.S. garrison in Seoul— to apologize for the "pain" caused by the alleged attacks on Saturday.

The top U.S. diplomat for East Asia, Kurt Campbell also released a statement, calling the incident a "tragic and inexcusable rape," according to the Associated Press. It was unclear which case he was referring to.

One of the soldiers, a private in his 20s, allegedly raped a girl in her rented room in the country's capital on Sept. 17. He has been questioned by police but hasn't been taken into custody.

The serviceman allegedly broke into the young woman's room while she was sleeping, raped her and then fled with her laptop computer, police told South Korea's Yonhap News Agency.

He told police they drank together the previous night and that the sex was consensual.

The other alleged rape occurred on Sept. 24 in Dongducheon, a city home to several military camps just north of Seoul. Few details from that incident have been released.

The allegations also resulted in America's top commander in the Asian country, Gen. James Thurman, to instate a curfew—midnight during the week and 3 a.m. on the weekend -- for the next 30 days due to "the incidents over the last several months."
